The combination of fast AF and accurate manual override gives you full creative control in dynamic situations.

Its design supports reliable performance in varied shooting environments, from bright studio setups to challenging outdoor scenes.
• Natural perspective with close focusing: at 50mm with a minimum focusing distance of 0.40 m (1.31 ft), you can framing portraits and details with a natural perspective that flatters subjects while still capturing environmental context when desired, making it a versatile choice for bloggers, documentary photographers, and creators who love a wide palette of framing options.
• Versatile accessory compatibility: the generous 54 mm front filter diameter accommodates a wide range of filters and accessories, enabling you to control reflections, contrast, and color balance.
